The Rolex Datejust is a classic timepiece that has been a mainstay in the world of luxury watches for over 70 years. The first Datejust model was introduced in 1945, and it was the first wristwatch to feature an automatically changing date display. This revolutionary feature was made possible by a new self-winding movement developed by Rolex, which also allowed the watch to have a more streamlined, sleek design. The Datejust represents the spirit of the Rolex by treading that fine line between an all-out dress piece and something robust and versatile enough to be worn every day.
